Abstract

We report experimentally and on theory on the controllable inhibition of spiking regimes in a 1300 nm wavelength Vertical Cavity Surface Emitting Laser (VCSEL). Reproducible suppression of spiking dynamics is demonstrated at fast operation speeds (up to sub-ns rates) and with total control on the temporal duration of the spiking inhibition windows. This work opens new paths towards photonic inhibitory neuronal model system for use in future neuromorphic photonic information processing modules and which are able to operate at speeds up to 8 orders of magnitude faster than biological neurons.
